      I setup my DMZ interface and attempted to do a net install of a Debian webserver only to figure out I need FW rules. So looking into several Dr Google recommendations/suggestions or guides attempted over and over. I even attempted to setup rules via Basic Firewall Configuration Example - which was very confusing to me. Most often the time server stuff would not resolve or the package manager could not connect to mirror. I was able to setup one rule allowing DMZ.net to any basically. This allowed me to complete an install of Debian successfully but I am pretty sure its not a good set of rules.

      So my question is what is a good secure DMZ rule set?

        The examples in your link are neat anyway. What's are your doubts?
        But you have to adapt the settings to fit your needs. We don't know these.

        If you want the devices to request pfSense for say DNS and NTP you need to allow these protocols to the interface address only.

          I'm pretty sure the rule below is not acceptable or secure however I am able to go through the install. My goal is to get through the net install and not have my LAN at risk.

            @digiguy maybe something like

            allow DMZ Net to This Firewall port 53 tcp/udp
            reject DMZ Net to This Firewall
            reject DMZ Net to LAN Net
            allow DMZ Net to any/*

            Pre-2.7.2/23.09: Only install packages for your version, or risk breaking it. Select your branch in System/Update/Update Settings.
            When upgrading, allow 10-15 minutes to restart, or more depending on packages and device speed.
